Samsung Refrigerator Error Code Humidity-Sensor

This error code means the refrigerator's control system has detected a fault in the humidity sensor circuit. The fault can be caused by the sensor housing separating from its mount, a contact error at the connector, a disconnected wiring harness, or a short circuit in the sensor wiring. The refrigerator displays this code to alert you that the humidity monitoring system is not operating correctly and needs inspection.

The refrigerator will likely continue cooling, but the humidity sensor fault can affect how the appliance manages moisture and defrost cycles. Over time this could lead to excessive frost buildup or inconsistent temperatures. It is advisable to have the fault diagnosed and repaired promptly rather than running the unit indefinitely with this error active.

A power reset may temporarily clear the error code from the display, but the code will return if the underlying wiring, connection, or sensor fault has not been corrected. Resetting without repairing the root cause is not a lasting solution and can delay proper diagnosis.

Some causes are within reach of a knowledgeable DIYer. You can inspect the sensor housing for physical separation, check that all connectors are fully seated, and look for visible wiring damage. However, testing the circuit properly requires a multimeter, and replacing a faulty sensor or wiring harness is best handled by someone comfortable working with appliance electronics.

Repair costs depend on the underlying cause. If the fix is simply reseating a connector, the cost is minimal and may only involve a service call fee, typically in the range of $75 to $150. If the humidity sensor itself needs replacement, parts and labor combined generally fall in the range of $100 to $250, depending on your location and the specific model.
